In this paper, we describe about the statistical distribution of eigenvalues of correlation matrices in independent and identically distributed (i.i.d.) MIMO Rayleigh fading channels. First, the statistical eigenanalysis of MIMO channel correlation matrices is carried out, and the exact expression of the marginal distribution of eigenvalues is presented. Then, a monomial approximation of above distribution with a simple form convenient for the calculation of MIMO performance is proposed based on the theory of space diversity in SIMO systems adopting maximal ratio combining. Through computer simulations, the effectiveness of the proposed approximation method is demonstrated
